Listen to Two Unreleased Amy Winehouse Tracks, Including a Nas Duet

"Like Smoke" and "Our Day Will Come"

The posthumous Amy Winehouse album Lioness: Hidden Treasures is scheduled for release on December 5 through Island. Among the previously unheard recordings on the album is Winehouse's collaboration with Nas on a song called "Like Smoke". MissInfo points to the Salaam Remi-produced song, which aired last night on New York's Hot97 -- listen to the collaboration here.

Along with "Like Smoke", MTV UK points to another cut from the album that was played last night on BBC's Radio 1. It's a reggaefied version of "Our Day Will Come", a song originally popularized in the early 1960s by Ruby & the Romantics. Listen to that track here.
